The Stages Power Cannondale Si HG is the power meter option for all Cannondale BB30 riders who are on a Cannondale Si HG crankset. The Stages Power Cannondale Si HG will also fit SISL2 and Si cranksets. The Stages Power is pre-assembled on a Cannondale Si HG left crankarm. It replaces the existing left crankarm which makes installation pretty simple. Due to the left crankarm interface there is no interference with the drivetrain components.
Via ANT+ and Bluetooth Smart technologies the Stages Power is compatible with all ANT+ cycling computers as well as with the latest smartphone models.
The new Stages Power meter is slimmer, and up to 28-percent lower profile than our original meter. It’s sleeker by way of a 17-percent reduction in frontal area, and we’ve also made it stronger. The new housing design increases the strength of the battery door and housing connection by 200-percent over the previous design.
